V8.x-PRE2 Serious PUC problem - Heads Up!

[Karl Denninger]

It appears that V8.x has changed some device names in the serial
subsystem, moving them to the "puc" naming (e.g. ttydxx moves to ttyuxx)

There is a fairly serious issue with Hylafax under the new setup that I
have not (yet) been able to run down.  It manifests as ports that simply
stop working, where they were fine under 7.x, after some indeterminate
period of time.

I will update as I have more information - this is a serious issue for
anyone who needs working serial ports on multiport cards under FreeBSD
for things like a fax server..... this is not the sort of "surprise" one
wants to see!
